title of the reference :  Origins of peri-Saharan dust deposits traced by their Nd and Sr isotopic composition.
Publication Date: 1992
Author : Grousset Francis, Rognon Pierre, Coude Gaussen G., Pedemay P.
Catalogue type : Livre
Catalogue reference : (NLD) Palaeogeogr., Palaeoclimatol., Palaeoecol. Origins of peri-Saharan dust deposits traced by their Nd and Sr isotopic composition. Isotopic ratios of Sr and Nd can be used as very precise tracers in conjunction with mineralogical, geochemical tracers and climatic models, to identify the origins of dust deposit and to quantify their fluxes, both today and throughout the last climatic cycles. This technique is useful for constraining aeolian transport and atmospheric circulation trajectories from desert sources and over the oceans. The present work concerns dust deposits surrounding the Saharan desert. On the Canary Islands, the African fraction of the dust deposits displays isotopic values which are typical of Moroccan origin.
